Hydraulic Breaker Piikki GA205 (50 - 70 t) 6800 kg
Green Attachments’ hydraulic breakers provide a powerful, durable, and reliable solution for all construction, demolition, and earthmoving tasks where brute force is needed to break through rock, concrete, and hard materials.
Our range covers models for mini-excavators all the way up to large crawler machines. Whether you're working on a demolition site, quarry, or major infrastructure project – we have the right tool for the job. Typical applications are excavation assistance, demolition etc.
The impact energy is generated by hydraulic pressure and nitrogen gas pressure together at the top of the piston. There is gas chamber (back head) at the top of the piston and isn’t included accumulator, thus this type of breaker is called “gas type breaker”. Gas Type Breakers have effective power and performance if you prefer economic investment. They can be operated comparatively at the higher back pressure than hydraulic type breaker.
Hydraulic Breaker applications
- demolition applications, concrete breaking
- frozen soil breaking
- rock breaking
- Slag breaking
- Reducing oversize material
- Road construction
- Sidewalk and curb construction
- Commercial / selective demolition
- Site excavation
- Trenching
Advantages of Piikki breakers:
- Low wear, resulting in high secondhand resale value of a breaker
- Low thermal heat of oil means energy savings for end user
- Good hydraulic shock absorption
- Less maintenance of hammers, and therefore lower costs
- Hammers have well designed hydraulics to minimize overheating
- The buffer system (side, top and bottom buffers) that is used in Piikki breakers, has a special impact and vibration absorbing properties
- Easy changing of tools
- Noise isolation sheets as standard
- Diameters of tool and piston are matched for maximum energy transfer
